BACKGROUND

When hanging items on a wall or other surface, it is well known thatsuch items can become undesirably misaligned. Such misalignment candetract from the pleasure of viewing the item. Currently, a viewer isrequired to move the misaligned item manually. Without the use a level,a viewer may have to approach the item, realign it, and then move adistance away from the item to determine whether the item has been movedback to the desired orientation. The viewer may have to repeat thisprocess numerous times in order to accurately move the item to thedesired orientation. Moreover, such manual alignment can often sparkcontroversy or disagreement between multiple viewers over whether theitem has, in fact, been returned to proper alignment. Improved methodsfor aligning items hung on a wall or surface are, therefore, desirable.

DETAILED DESCRIPTION

Various embodiments of the invention relate to an apparatus that may beattached to, and which automatically adjusts and levels, hangingpictures, other square, rectangle or other shaped objects i.e., Framesor Works, and methods for their use.

Various embodiments of the present invention provide an inexpensive, andeasy to use apparatus and method that permits a User to attach anapparatus to existing Frames with various advantages. Such embodimentswill keep a picture or other object or Frame in a substantiallycontinuously level position or otherwise Aligned position. Thus, a Usercan ensure that any Frame or other hanging and relatively flat objectwill generally remain in a pleasantly horizontal or other desiredaspect, without need for ongoing User inspection or manual adjustment.

In some circumstances, various embodiments of the present invention maybe adapted for use in conjunction with many known devices and, thereforeis an improvement upon, several of the previously known inventions.

Various embodiments of the present invention address the need to providea leveling device for existing or traditional Frames or other objects,and the need to provide for any ongoing automatic adjustments.

Various embodiments of the present invention address the problem of apicture hung “out of level” and corrects such pictures if there is usererror upon initial installation or subsequent manual adjustment of thedevice(s) or frames.

Various embodiments of the present invention may be readily employedwith the millions of existing, popular and widely used picture framesand other Frames that are hung using the well known and widely adopted“hook and wire” hardware as depicted in FIG. 1C showing a Hook 15 andwire 14.

Various embodiments of the present invention work effectively withexisting picture frames and other hanging objects, without the need formajor modifications to the frames or objects, nor changes to widelyaccepted practices, nor any particular skills or craftsmanship by theUser.

Various embodiments of the present invention permit a Frame that isnudged or that is otherwise not properly Aligned to be automaticallyreturned to its Aligned position.

An embodiment of the present invention includes an apparatus forautomatically adjusting and leveling hanging pictures or other Frames orobjects, and methods for use of such an apparatus. In an embodiment, thedevice comprises seven main components including a (an):

-   -   1. Enclosure    -   2. Dual Throw, Dual Pole Tilt Switch (or other device(s) for        determining misalignment)    -   3. Direct Current (DC) Motor (or other power source or motor        type)    -   4. Battery (or other power source)    -   5. A Wheel attached to the Motor via a Gear    -   6. Wiring connecting the Tilt Switch, Battery, Motor and, if        included, Solar Charger.    -   7. Solar Charger (or other means for recharging a battery or        other power source)

It is readily apparent to one of ordinary skill in the art that varioussubstitutions may be made to the specific components listed immediatelyabove.

When mounted to the lower right corner (or, e.g., the lower left cornerwith minor and apparent modifications) of a Frame or other object, theapparatus is activated whenever the Frame or object becomes misaligned.When either corner is lowered, the integral Tilt Switch “senses” thismisalignment and an electrical circuit is created or closed. Thiselectrical circuit, in turn, supplies power (in the form of anelectrical current) to a DC motor, which causes the DC motor to turn,which then turns a Gear that is further attached to a Wheel. This Wheelis positioned in the apparatus such that, when attached to the Frame,the Wheel will come in direct contact with the adjacent wall or otherstationary mounting object. When the Wheel turns, the Frame is moved,e.g., up or down, at the corner where the device is attached, therebyrealigning the Frame or object.

For example, in the event that the lower right corner of the Frame (orobject) is too low, a Motor turns a Wheel in a clockwise direction (whenviewing the device from the right side of the Frame), which pushes thelower right corner of the Frame (or object) up the wall (or alongwhatever the Frame or object may be attached).

In the event that the lower right corner of the Frame is too high, theTilt Switch is engaged such that the polarity of the current isreversed, causing the motor to turn in a counter-clockwise direction(when viewing the device from the right side of the frame), which causesthe right corner to move lower in relation to the wall.

In either case, as the Frame (or object or Work) returns to properalignment, e.g., level with the floor (or Earth), the Tilt Switch isreturned to the “null” position, which opens the previously establishedcircuit. Without power, the motor ceases to turn, causing the wheel tostop. In this fashion, the Frame remains in a consistently Alignedposition. Furthermore, battery or other electrical power is conserved assuch power is generally consumed when the Frame is misaligned.

An embodiment of the present invention includes a buzzer or other devicecapable of generating a sound, which may alert the User that theapparatus is functioning.

An embodiment of the present invention includes a Light Emitting Diode(LED) or other device capable of generating visible light, which mayalert the User that the apparatus is functioning.

Various other embodiments are described.

Definitions

Terms

-   -   a. Aligned—shall mean aligned in a desired manner, such as        substantially level with the earth. In an embodiment, aligned        means that a portion of the object that is desired to be aligned        (e.g., a portion such as a bottom horizontal edge) lies        substantially in the plane that is normal (perpendicular) to the        axis defined by the direction of gravity. This plane is referred        to as the “horizontal plane”. In such an embodiment, the portion        of the object (e.g., the bottom edge) would be substantially        perpendicular to the axis defined by the direction of gravity,        and where the portion defines an axis, such an axis lies        substantially in the horizontal plane (but may form a small        angle with respect to the horizontal plane). Thus, ‘aligned’ can        mean aligned within a threshold number of degrees (e.g., within        5 degrees) of a plane (e.g., the horizontal plane). In other        embodiments, an object or portion of the object is aligned with        respect to a plane that is not coincident with the horizontal        plane. For example, it may be desirable to align an object or        portion of an object    -   b. User-shall mean any person including a person making use or        practicing the various disclosed embodiments of the invention.    -   c. Frame—shall mean a structure or framework supporting or        containing something or in which a picture is mounted, or any        other fixtures, such as a mirror, commercial signage or other        similar objects that may be hung, e.g., on a wall or other base.    -   d. Work—shall mean an object, including but not limited to, a        picture, painting, mirror or poster that is contained within a        Frame or other border materials.    -   e. Tilt Switch—shall mean a device (whether or not commercially        available or custom manufactured) that is capable of detecting a        change in orientation on a single axis or on multiple axes. A        Tilt Switch may include, but is not limited to any one (or more,        as necessary or desired) of the following devices: a        Single-Pole, Double-Throw (SPDT) mercury tilt switch, pendulum        inclinator or tilt switch, “ball in tube” tilt switch or any        solid state, liquid filled, electrolytic inclinometer/tilt        sensor, or any other suitable tilt sensing device.    -   f. Motor—shall mean a (commercially available or custom        manufactured) Direct Current (DC) Motor or any other suitable        device(s) that convert electrical current into mechanical or        physical motion.    -   g. Solar Charger—shall mean a device (whether such device is        commercially available or custom manufactured) that is capable        of converting sunlight, ambient light, or other light (whether        or not considered “visible light”) or other electromagnetic        radiation into an electrical current using one or more        transducers (e.g., photovoltaic cells) and may include a        regulation device to prevent overcharging.    -   h. The term “product” means any machine, manufacture and/or        composition of matter, unless expressly specified otherwise.    -   i. The term “process” means any process, algorithm, method or        the like, unless expressly specified otherwise.    -   j. Each process (whether called a method, algorithm or        otherwise) inherently includes one or more steps, and therefore        all references to a “step” or “steps” of a process have an        inherent antecedent basis in the mere recitation of the term        ‘process’ or a like term. Accordingly, any reference in a claim        to a ‘step’ or ‘steps’ of a process has sufficient antecedent        basis.    -   k. The terms “an embodiment”, “embodiment”, “embodiments”, “the        embodiment”, “the embodiments”, “one or more embodiments”, “some        embodiments”, “certain embodiments”, “one embodiment”, “another        embodiment” and the like mean “one or more (but not all)        embodiments of the disclosed invention(s)”, unless expressly        specified otherwise.    -   l. The term “variation” of an invention means an embodiment of        the invention, unless expressly specified otherwise.    -   m. A reference to “another embodiment” in describing an        embodiment does not imply that the referenced embodiment is        mutually exclusive with another embodiment (e.g., an embodiment        described before the referenced embodiment), unless expressly        specified otherwise.    -   n. The terms “including”, “comprising” and variations thereof        mean “including but not limited to”, unless expressly specified        otherwise.    -   o. The term “consisting of” and variations thereof mean        “including and limited to”, unless expressly specified        otherwise.    -   p. The terms “a”, “an” and “the” mean “one or more”, unless        expressly specified otherwise.    -   q. The term “plurality” means “two or more”, unless expressly        specified otherwise.    -   r. The term “herein” means “in this patent application,        including anything which may be incorporated by reference”,        unless expressly specified otherwise.    -   s. The phrase “at least one of”, when such phrase modifies a        plurality of things (such as an enumerated list of things) means        any combination of one or more of those things, unless expressly        specified otherwise. For example, the phrase “at least one of a        widget, a car and a wheel” means either (i) a widget, (ii) a        car, (iii) a wheel, (iv) a widget and a car, (v) a widget and a        wheel, (vi) a car and a wheel, or (vii) a widget, a car and a        wheel.    -   t. Numerical terms such as “one”, “two”, etc. when used as        cardinal numbers to indicate quantity of something (e.g., one        widget, two widgets), mean the quantity indicated by that        numerical term, but do not mean at least the quantity indicated        by that numerical term. For example, the phrase “one widget”        does not mean “at least one widget”, and therefore the phrase        “one widget” does not cover, e.g., two widgets.    -   u. The phrase “based on” does not mean “based only on”, unless        expressly specified otherwise. In other words, the phrase “based        on” describes both “based only on” and “based at least on”.    -   v. The term “represent” and like terms are not exclusive, unless        expressly specified otherwise. For example, the term        “represents” does not mean “represents only”, unless expressly        specified otherwise. In other words, the phrase “the data        represents a credit card number” describes both “the data        represents only a credit card number” and “the data represents a        credit card number and the data also represents something else”.    -   w. The term “whereby” is used herein only to precede a clause or        other set of words that express only the intended result,        objective or consequence of something that is previously and        explicitly recited. Thus, when the term “whereby” is used in a        claim, the clause or other words that the term “whereby”        modifies do not establish specific further limitations of the        claim or otherwise restricts the meaning or scope of the claim.    -   x. The term “e.g.” and like terms means “for example”, and thus        does not limit the term or phrase it explains. For example, in        the sentence “the computer sends data (e.g., instructions, a        data structure) over the Internet”, the term “e.g.” explains        that “instructions” are an example of “data” that the computer        may send over the Internet, and also explains that “a data        structure” is an example of “data” that the computer may send        over the Internet. However, both “instructions” and “a data        structure” are merely examples of “data”, and other things        besides “instructions” and “a data structure” can be “data”.    -   y. The term “i.e.” and like terms means “that is”, and thus        limits the term or phrase it explains. For example, in the        sentence “the computer sends data (i.e., instructions) over the        Internet”, the term “i.e.” explains that “instructions” are the        “data” that the computer sends over the Internet.

Determining/Sensing

-   -   a. The terms “determine”, “sense”, “determining”, or “sensing”        and grammatical variants thereof (e.g., to determine a price,        determining a value, sensing an angle, determine an object which        meets a certain criterion) is used in an extremely broad sense.        The terms “determine” “sense” “determining” or “sensing”        encompasses a wide variety of actions and therefore can include        calculating, computing, processing, examining, deriving,        investigating, looking up (e.g., looking up in a table, a        database or another data structure), ascertaining and the like.        Also, “determine”, “sense”, “determining”, or “sensing” can        include receiving (e.g., receiving information), accessing        (e.g., accessing data in a memory), the closing an electrical        circuit” and the like and can also include resolving, selecting,        choosing, establishing, and the like.    -   b. The terms “determine”, “sense”, “determining”, or “sensing”        does not imply certainty or absolute precision, and therefore        can include estimating, predicting, guessing and the like.    -   c. The terms “determine”, “sense”, “determining”, or “sensing”        does not imply that mathematical processing must be performed,        and does not imply that numerical methods must be used, and does        not imply that an algorithm or process is used.    -   d. The terms “determine”, “sense”, “determining”, or “sensing”        does not imply that any particular device must be used. For        example, a computer need not necessarily perform the determining        or sensing.

Forms of Sentences

-   -   a. Where a limitation of a first claim would cover one of a        feature as well as more than one of a feature (e.g., a        limitation such as “at least one widget” covers one widget as        well as more than one widget), and where in a second claim that        depends on the first claim, the second claim uses a definite        article “the” to refer to the limitation (e.g., “the widget”),        this does not imply that the first claim covers only one of the        feature, and this does not imply that the second claim covers        only one of the feature (e.g., “the widget” can cover both one        widget and more than one widget).    -   b. Each claim in a set of claims has a different scope.        Therefore, for example, where a limitation is explicitly recited        in a dependent claim, but not explicitly recited in any claim        from which the dependent claim depends (directly or indirectly),        that limitation is not to be read into any claim from which the        dependent claim depends.    -   c. When an ordinal number (such as “first”, “second”, “third”        and so on) is used as an adjective before a term, that ordinal        number is used (unless expressly specified otherwise) merely to        indicate a particular feature, such as to distinguish that        particular feature from another feature that is described by the        same term or by a similar term. For example, a “first widget”        may be so named merely to distinguish it from, e.g., a “second        widget”. Thus, the mere usage of the ordinal numbers “first” and        “second” before the term “widget” does not indicate any other        relationship between the two widgets, and likewise does not        indicate any other characteristics of either or both widgets.        For example, the mere usage of the ordinal numbers “first” and        “second” before the term “widget” (1) does not indicate that        either widget comes before or after any other in order or        location; (2) does not indicate that either widget occurs or        acts before or after any other in time; and (3) does not        indicate that either widget ranks above or below any other, as        in importance or quality. In addition, the mere usage of ordinal        numbers does not define a numerical limit to the features        identified with the ordinal numbers. For example, the mere usage        of the ordinal numbers “first” and “second” before the term        “widget” does not indicate that there must be no more than two        widgets.    -   d. When a single device or article is described herein, more        than one device/article (whether or not they cooperate) may        alternatively be used in place of the single device/article that        is described. Accordingly, the functionality that is described        as being possessed by a device may alternatively be possessed by        more than one device/article (whether or not they cooperate).    -   e. Similarly, where more than one device or article is described        herein (whether or not they cooperate), a single device/article        may alternatively be used in place of the more than one device        or article that is described. For example, a plurality of        computer-based devices may be substituted with a single        computer-based device. Accordingly, the various functionality        that is described as being possessed by more than one device or        article may alternatively be possessed by a single        device/article.    -   f. The functionality and/or the features of a single device that        is described may be alternatively embodied by one or more other        devices which are described but are not explicitly described as        having such functionality/features. Thus, other embodiments need        not include the described device itself, but rather can include        the one or more other devices which would, in those other        embodiments, have such functionality/features.

Disclosed Examples and Terminology Are Not Limiting

-   -   a. Numerous embodiments are described in this patent        application, and are presented for illustrative purposes only.        The described embodiments are not, and are not intended to be,        limiting in any sense. The presently disclosed invention(s) are        widely applicable to numerous embodiments, as is readily        apparent from the disclosure. One of ordinary skill in the art        will recognize that the disclosed invention(s) may be practiced        with various modifications and alterations, such as structural,        logical, software, and electrical or electromechanical        modifications. Although particular features of the disclosed        invention(s) may be described with reference to one or more        particular embodiments and/or drawings, it should be understood        that such features are not limited to usage in the one or more        particular embodiments or drawings with reference to which they        are described, unless expressly specified otherwise.    -   b. The present disclosure is neither a literal description of        all embodiments of the invention nor a listing of features of        the invention which must be present in all embodiments.    -   c. Neither the Title (set forth at the beginning of the first        page of this patent application) nor the Abstract (set forth at        the end of this patent application) is to be taken as limiting        in any way as the scope of the disclosed invention(s). An        Abstract has been included in this application merely because an        Abstract of not more than 150 words is required under 37 C.F.R.        §1.72(b).    -   d. The title of this patent application and headings of sections        provided in this patent application are for convenience only,        and are not to be taken as limiting the disclosure in any way.    -   e. Devices that are described as in communication or otherwise        connected with each other need not be in continuous        communication or connection with each other, unless expressly        specified otherwise. On the contrary, such devices need only        transmit or be otherwise connected to each other as necessary or        desirable, and may actually refrain from exchanging data or        electrical current most of the time. For example, a machine in        communication with another machine via the Internet may not        transmit data to the other machine for a prolonged period (e.g.        weeks at a time). In addition, devices that are in communication        with each other may communicate directly or indirectly through        one or more intermediaries.    -   f. A description of an embodiment with several components or        features does not imply that all or even any of such        components/features are required. On the contrary, a variety of        optional components are described to illustrate the wide variety        of possible embodiments of the present invention(s). Unless        otherwise specified explicitly, no component/feature is        essential or required.    -   g. Although process steps, algorithms or the like may be        described in a sequential order, such processes may be        configured to work in different orders. In other words, any        sequence or order of steps that may be explicitly described does        not necessarily indicate a requirement that the steps be        performed in that order. On the contrary, the steps of processes        described herein may be performed in any order practical.        Further, some steps may be performed simultaneously despite        being described or implied as occurring non-simultaneously        (e.g., because one step is described after the other step).        Moreover, the illustration of a process by its depiction in a        drawing does not imply that the illustrated process is exclusive        of other variations and modifications thereto, does not imply        that the illustrated process or any of its steps are necessary        to the invention, and does not imply that the illustrated        process is preferred.    -   h. Although a process may be described as including a plurality        of steps, that does not imply that all or any of the steps are        essential or required. Various other embodiments within the        scope of the described invention(s) include other processes that        omit some or all of the described steps. Unless otherwise        specified explicitly, no step is essential or required.    -   i. Although a product may be described as including a plurality        of components, aspects, qualities, characteristics and/or        features, that does not indicate that all of the plurality are        essential or required. Various other embodiments within the        scope of the described invention(s) include other products that        omit some or all of the described plurality.    -   j. Unless expressly specified otherwise, an enumerated list of        items (which may or may not be numbered) does not imply that any        or all of the items are mutually exclusive. Therefore it is        possible, but not necessarily true, that something can be        considered to be, or fit the definition of, two or more of the        items in an enumerated list. Also, an item in the enumerated        list can be a subset (a specific type of) of another item in the        enumerated list. For example, the enumerated list “a computer, a        laptop, a PDA” does not imply that any or all of the three items        of that list are mutually exclusive—e.g., an item can be both a        laptop and a computer, and a “laptop” can be a subset of (a        specific type of) a “computer”.    -   k. Likewise, unless expressly specified otherwise, an enumerated        list of items (which may or may not be numbered) does not imply        that any or all of the items are collectively exhaustive or        otherwise comprehensive of any category. For example, the        enumerated list “a computer, a laptop, a PDA” does not imply        that any or all of the three items of that list are        comprehensive of any category.    -   l. Further, an enumerated listing of items does not imply that        the items are ordered in any manner according to the order in        which they are enumerated.

Computing

-   -   a. It will be readily apparent to one of ordinary skill in the        art that the various processes described herein may be        implemented by, e.g., appropriately programmed general purpose        computers and computing devices. Typically a processor (e.g.,        one or more microprocessors, one or more microcontrollers, one        or more digital signal processors) will receive instructions        (e.g., from a memory or like device), and execute those        instructions, thereby performing one or more processes defined        by those instructions.    -   b. A “processor” means one or more microprocessors, central        processing units (CPUs), computing devices, microcontrollers,        digital signal processors, or like devices or any combination        thereof.    -   c. Thus a description of a process is likewise a description of        an apparatus for performing the process. The apparatus can        include, e.g., a processor and those input devices and output        devices that are appropriate to perform the method.    -   d. Further, programs that implement such methods (as well as        other types of data) may be stored and transmitted using a        variety of media (e.g., computer readable media) in a number of        manners. In some embodiments, hard-wired circuitry or custom        hardware may be used in place of, or in combination with, some        or all of the software instructions that can implement the        processes of various embodiments. Thus, various combinations of        hardware and software may be used instead of software or        hardware only.    -   e. The term “computer-readable medium” refers to any medium that        participates in providing data (e.g., instructions, data        structures) which may be read by a computer, a processor or a        like device. Such a medium may take many forms, including but        not limited to, non-volatile media, volatile media, and        transmission media. Non-volatile media include, for example,        optical or magnetic disks and other persistent memory. Volatile        media include dynamic random access memory (DRAM), which        typically constitutes the main memory. Transmission media        include coaxial cables, copper wire and fiber optics, including        the wires that comprise a system bus coupled to the processor.        Transmission media may include or convey acoustic waves, light        waves and electromagnetic emissions, such as those generated        during radio frequency (RF) and infrared (IR) data        communications. Common forms of computer-readable media include,        for example, a floppy disk, a flexible disk, hard disk, magnetic        tape, any other magnetic medium, a CD-ROM, DVD, any other        optical medium, punch cards, paper tape, any other physical        medium with patterns of holes, a RAM, a PROM, an EPROM, a        FLASH-EEPROM, any other memory chip or cartridge, a carrier wave        as described hereinafter, or any other medium from which a        computer can read.    -   f. Various forms of computer readable media may be involved in        carrying data (e.g. sequences of instructions) to a processor.        For example, data may be (i) delivered from RAM to a        processor; (ii) carried over a wireless transmission        medium; (iii) formatted and/or transmitted according to numerous        formats, standards or protocols, such as Ethernet (or IEEE        802.3), SAP, ATP, Bluetooth, and TCP/IP, TDMA, CDMA, and 3G;        and/or (iv) encrypted to ensure privacy or prevent fraud in any        of a variety of ways well known in the art.    -   g. Thus a description of a process is likewise a description of        a computer-readable medium storing a program for performing the        process. The computer-readable medium can store (in any        appropriate format) those program elements which are appropriate        to perform the method.    -   h. Just as the description of various steps in a process does        not indicate that all the described steps are required,        embodiments of an apparatus include a computer/computing device        operable to perform some (but not necessarily all) of the        described process.    -   i. Likewise, just as the description of various steps in a        process does not indicate that all the described steps are        required, embodiments of a computer-readable medium storing a        program or data structure include a computer-readable medium        storing a program that, when executed, can cause a processor to        perform some (but not necessarily all) of the described process.    -   j. Where databases are described, it will be understood by one        of ordinary skill in the art that (i) alternative database        structures to those described may be readily employed, and (ii)        other memory structures besides databases may be readily        employed. Any illustrations or descriptions of any sample        databases presented herein are illustrative arrangements for        stored representations of information. Any number of other        arrangements may be employed besides those suggested by, e.g.,        tables illustrated in drawings or elsewhere. Similarly, any        illustrated entries of the databases represent exemplary        information only; one of ordinary skill in the art will        understand that the number and content of the entries can be        different from those described herein. Further, despite any        depiction of the databases as tables, other formats (including        relational databases, object-based models and/or distributed        databases) are well known and could be used to store and        manipulate the data types described herein. Likewise, object        methods or behaviors of a database can be used to implement        various processes, such as the described herein. In addition,        the databases may, in a known manner, be stored locally or        remotely from any device(s) which access data in the database.    -   k. Various embodiments can be configured to work in a network        environment including a computer that is in communication (e.g.,        via a communications network) with one or more devices. The        computer may communicate with the devices directly or        indirectly, via any wired or wireless medium (e.g. the Internet,        LAN, WAN or Ethernet, Token Ring, a telephone line, a cable        line, a radio channel, an optical communications line,        commercial on-line service providers, bulletin board systems, a        satellite communications link, a combination of any of the        above). Each of the devices may themselves comprise computers or        other computing devices, such as those based on the Intel®        Pentium® or Centrino™ processor, that are adapted to communicate        with the computer. Any number and type of devices may be in        communication with the computer.    -   l. In an embodiment, a server computer or centralized authority        may not be necessary or desirable. For example, the present        invention may, in an embodiment, be practiced on one or more        devices without a central authority. In such an embodiment, any        functions described herein as performed by the server computer        or data described as stored on the server computer may instead        be performed by or stored on one or more such devices.

-   -   a. The present disclosure provides, to one of ordinary skill in        the art, an enabling description of several embodiments and/or        inventions. Some of these embodiments and/or inventions may not        be claimed in this patent application, but may nevertheless be        claimed in one or more continuing applications that claim the        benefit of priority of this patent application. Applicants        intend to file additional applications to pursue patents for        subject matter that has been disclosed and enabled but not        claimed in this patent application.

35U.S.C. § 112, Paragraph 6

-   -   a. In a claim, a limitation of the claim which includes the        phrase “means for” or the phrase “step for” means that 35 U.S.C.        §112, paragraph 6, applies to that limitation.    -   b. In a claim, a limitation of the claim which does not include        the phrase “means for” or the phrase “step for” means that 35        U.S.C. §112, paragraph 6 does not apply to that limitation,        regardless of whether that limitation recites a function without        recitation of structure, material or acts for performing that        function. For example, in a claim, the mere use of the phrase        “step of” or the phrase “steps of” in referring to one or more        steps of the claim or of another claim does not mean that 35        U.S.C. §112, paragraph 6, applies to that step(s).    -   c. With respect to a means or a step for performing a specified        function in accordance with 35 U.S.C. §112, paragraph 6, the        corresponding structure, material or acts described in the        specification, and equivalents thereof, may perform additional        functions as well as the specified function.    -   d. Computers, processors, computing devices and like products        are structures that can perform a wide variety of functions.        Such products can be operable to perform a specified function by        executing one or more programs, such as a program stored in a        memory device of that product or in a memory device which that        product accesses. Unless expressly specified otherwise, such a        program need not be based on any particular algorithm, such as        any particular algorithm that might be disclosed in this patent        application. It is well known to one of ordinary skill in the        art that a specified function may be implemented via different        algorithms, and any of a number of different algorithms would be        a mere design choice for carrying out the specified function.    -   e. Therefore, with respect to a means or a step for performing a        specified function in accordance with 35 U.S.C. §112, paragraph        6, structure corresponding to a specified function includes any        product programmed to perform the specified function. Such        structure includes programmed products which perform the        function, regardless of whether such product is programmed        with (i) a disclosed algorithm for performing the function, (ii)        an algorithm that is similar to a disclosed algorithm, or (iii)        a different algorithm for performing the function.

DESCRIPTION OF VARIOUS EMBODIMENTS

While the invention is susceptible to various modifications andalternative constructions, certain illustrated embodiments thereof havebeen shown in the drawings and will be described below in detail. Itshould be understood, however, that there is no intention to limit theinvention to the specific form disclosed, but, on the contrary, theinvention is to cover all modifications, alternative constructions,substituted materials, devices or electrical components, wiring, and thelike including any and all equivalents falling within the spirit andscope of the claims.

Referring concurrently to FIGS. 1 and 3 of the drawings, details areprovided for an apparatus, which, as designed, is responsive to changesin angle of the Frame 17, so as to prevent the Frame 17 from remainingin a misaligned state. Tilt Switches 2, also known as inclinometers, arewell known and widely used, and are appropriate for use in variousembodiments of the present invention and are commercially available in avariety of styles and types, with and without the use of mercury, otherliquid electrolyte or other conductors. Therefore, only a briefdescription of generic tilt switches will be provided below. By way ofexample, one suitable tilt switch to be used herein is a mercury tiltswitch that is manufactured by RXR Electronics of Avenel, N.J. as PartNo. 1700TLMC. Another alternative would be use of a single or dual tiltsensors manufactured by Signal Quest of Lebanon N.H., as Part No.SQ-SEN-001P/001PS. Various alternative part selections andimplementations are readily apparent to anyone skilled in the art.However, a new Dual-Pole, Double-Throw (DPDT) Tilt Switch is disclosedherein and is ideally suited for use with various embodiments.

Alternatively, single or dual, solid-state single or dual axisinclinometers could be used such as those manufactured by Spectron ofHauppauge, N.Y. as Part No. TAD II. This option provides for athreshold, which may be adjusted by the user, and this threshold maydetermine the target angle, which is deemed the horizontal, or otherdesired angle of alignment.

Other types of inclinometers, and other devices, which determine aninclination with respect to the horizontal (i.e. the plane that isnormal to the axis defined by the direction of gravity or other angle ofdesired alignment) exist and are well known to those skilled in the art.

In an embodiment, a dual throw, dual pole switch such as that describedabove and further defined below and in Diagram 4.b would be employed asa component of the disclosed apparatus.

The Motor 3 and Tilt switch 2 shown in FIGS. 1A-1D is enclosed by anouter protective casing 19. A mounting bracket with screw holes 27 isaffixed to the casing 19 to enable the Leveling Apparatus to be attachedto the rear of the picture Frame 17 or other object to be aligned.

In another embodiment, Casing 19 may include dual-sided adhesive tape 25(FIG. 1B) instead of a mounting bracket and screw holes 27, which may beused to secure the apparatus to the Frame 17 without penetrating theFrame 17, or permanently or otherwise marring and/or damaging the Frame17.

As shown in the embodiment depicted in FIG. 4B, the control Tilt Switchincludes a hollow glass vial 10 that is suspended at the interior of theouter casing 20. The vial is shown having left and right chambers 21 and22 that are angled slightly upward relative to the center section of thevial. A supply of mercury 9 or any other suitable electricallyconductive liquid (or other conductor such as, e.g., a electricallyconductive metal ball) is carried within the hollow vial 10. First endsof a dual pair of electrical switch contacts 11 and 12 are separatedfrom one another at the interior of the vial 10 at either end 21 and 22of the chamber 20 thereof. The opposite ends of switch contacts 11 and12 are connected to respective electrical wires as more fully describedin FIGS. 3A and 3B. The electrical wires 11 and 12 complete theaforementioned control circuit so that the Tilt Switch 2 and the Motor 3may be connected in an electrical series with one another to control theoperation of the Motor 3 in a manner that will be disclosed furtherbelow and as depicted in the wiring diagrams in FIGS. 3A and 3B.

By connecting a Tilt Switch(es) 2, Motor 3, Battery 4, Pressure Wheel 5,Gear 6, with wiring according to FIG. 3A or, FIG. 3B (as appropriate, orwith other wiring assemblies that would be readily apparent to anyoneskilled in the art) the resulting apparatus can be attached to, e.g.,the bottom right edge of any picture, Frame, Work or object. Once inplace, with a charged battery or other power source installed orattached, the apparatus will automatically adjust a Frame 17, e.g., upor down until the Frame is realigned as desired. Note that Wheel 5 mayor may not include materials to aid in generating traction or friction.For example, Wheel 5 may be constructed of semi-pliable or hard plasticor rubber or it may have a rubber coating or layer, or groves or treadsto aid in generating friction. Other coatings on the Wheel may beemployed to generate appropriate amounts of friction with the applicablesurfaces, and/or the Wheel 5 may be composed of other materials togenerate appropriate amounts of friction with the applicable surfaces.

Upon closer inspection of FIGS. 3A and 3B, anyone skilled in the artwill notice that both Motor 3 electrical contacts are connected to bothpositive and negative wiring posts, which is ultimately attached toBattery 4. With proper installation of the Tilt Switch(es) 2, it will bereadily apparent that only a single circuit can be engaged (or closed)at any given moment depending upon the angle of inclination of the TiltSwitch(es). This novel arrangement provides a reversal of polarity,which permits the apparatus to deliver selective motion or movement,e.g., to deliver up or down movement of the Frame 17 in a manner whichachieves alignment.

FIG. 3A assumes the use of a novel Dual Pole, Dual Throw Tilt Switch asfurther disclosed herein; however, an alternative method is disclosedusing two Single-Pole, Double-Throw (SPDT) Tilt Switches as seen in FIG.3 B. In either depicted case, the depicted wiring ensures that only onecircuit with a given polarity is closed at any given time, thusprotecting the Motor 3 from any electromechanical failure and onlydelivering the desired movement of the Frame 17.

In an embodiment the apparatus derives its power from a single Battery4. As an example, the Battery 4 could be a single AA battery, such asone manufactured by Energizer of St. Louis, Mo. as Part No. EnergizerMax E91 AA Alkaline Battery or any other commercially available batteryor batteries as required or desirable in light of criteria such as thespecifically selected motor type employed including the motor's amperageand the voltage requirements.

A 0.7 Watt (or alternative voltage) DC motor could be used such as onemanufactured by Danaher Motion of Wood Dale, Ill. as Part No. 08G. Analternative motor might be one such as a 1.5-3V DC Metal Gear Motor asmanufactured by Radio Shack of Forth Worth, Tex. as their Model #:273-258 Catalog #: 273-258. It would be apparent to anyone skilled inthe art to construct the disclosed apparatus using a variety ofgenerally available DC or other motors, tilt switches, batteries or ACpower supplies, gears, wheels, wiring methods, wires and otherelectrical and/or mechanical components, adapting the enclosure, motorsize/horse power, battery voltage/amperage, or other power supply andother components to satisfy the apparatus' intended use, so that theapparatus provides the required response to a given weight and sizerequirement of various available Frames.

By way of example, but in no way limiting the general spirit and scopeof the potential of the various embodiments, it is anticipated that inan embodiment commercial implementations of an apparatus can be madeavailable in a predetermined number of sizes (e.g., three sizes—small,medium, and large). With different sizes, it may be desirable to adjustthe components and power of each apparatus accordingly so as to keep thedevice's cost and size to a minimum while providing ample power toperform acceptably within the target environment.

In an embodiment, use of the apparatus by a User can be accomplished viathe following method or steps: A Frame 17, such as that depicted in FIG.1C is first modified by attaching the Leveling Apparatus to the lowerportion of the backside (i.e., the side facing to the wall or adjacentmounting surface or structure, when the picture is hung), right edge ofthe Frame 17. This may be accomplished using double sided adhesive tape25 as seen in FIG. 1B, other forms of adhesive (either permanent ortemporary), or with small wood screws via mounting bracket frame holes27 as seen in FIGS. 1A and 1D or with any other method of affixing,adhering, connecting or attaching the apparatus to the Frame 17. Manyother methods of affixing a device, either temporarily or permanently,are well known within the prior art.

In an embodiment, when an appropriate Battery 4 is included (and/oralong with an optional power switch or other mechanism that controlspower—not shown, that is turned to the on position or otherwiseactivated), the apparatus is enabled to operate automatically. When theFrame 17 becomes misaligned, the Tilt Switch 2 is caused to be in an“out of level” or misaligned condition as well, which, in turn causes,e.g., the Mercury 9 to come into contact with the Electrical Leads,e.g., 11 or 12 and a circuit is formed or closed. The mercury could bereplaced with an electrically conducting metal ball or sphere, whichwould make the Tilt Switch shown in FIG. 4B more environmentallyfriendly without degrading performance. Many other mechanisms may beused for causing an electrical connection to be formed when the tiltswitch or other sensor is in a misaligned condition or state, all ofwhich are well known within the prior art.

If the apparatus is installed on the lower right edge of the object asdescribed herein, and the Frame 17 is tilted down on that right side,i.e., the right side of the Frame 17 is lower than that of the leftside, then the Tilt Switch 2 likewise is tilted down on that same rightside and a circuit is closed within the right side of the Tilt Switch 2,which, in turn, causes electrical power from the Battery 4 to besupplied to the Motor 3. This, in turn, causes the Gear 6 to turn theWheel 5 to turn clockwise (when facing from the right edge of theframe), which, in turn, causes the Frame 17 to “rise” on the right edgeand thus the left side to “fall” i.e., lower. The movement of the Frame17 is caused by the combination of the Wheel 5 turning and frictiongenerated when the Wheel 5 is resting against a generally solid andgenerally unmovable object, such as a wall. Friction between the Wheel 5and a wall, for example, causes the Frame 17 to move inversely to thedirection of the Wheel 5. To improve friction, a Wheel 5 may be designedto enhance the friction. Such enhancement may be accomplished innumerous ways including designing the Wheel 5 similarly to thosedepicted in FIG. 2C or 2D, which includes raised portions on the Wheel'ssurface. Moreover, the Wheel 5 may be made of a soft rubber or otherpliable or semi-adhesive compound to ensure adequate friction while alsoensuring that the movement of the Wheel 5 does not mar or otherwisedamage the mounting surface such as a wall.

Once the Frame is returned to the level state or other desiredorientation, i.e., is realigned, the Mercury 9 in the Tilt Switch 2 (or,e.g., metal ball or other conductor) returns to its neutral, i.e.,“null” or centered position which causes the circuit to open, this thencauses the Motor 3, Gear 6, and Wheel 5 to stop turning, whilesimultaneously conserving Battery 4 power for future usage.

In the case that the right edge of the Frame 17 is too high, in asimilar fashion, the opposite circuit of the Tilt Switch 2, is closed,thus providing Battery 4 power to the Motor 3 but with reverse polarity(i.e., opposite the polarity used in the previous example), which, inturn, causes the Motor 3, Gear 6, and Wheel 5 to spin in the opposite(i.e., counter-clockwise) direction, which, in turn, causes the rightedge of the Frame 17 to “fall” or lower. As before, as the Frame 17returns to its original alignment, e.g., a level condition, the circuitis once again opened and the Motor 3 stops, causing the Frame 17 to stopmoving as well.

The Motor 3 is coupled with an appropriate Battery 4 and Gear 6 so thatthe Leveling Apparatus is designed to operate and adjust the Frame 17slowly, such that the Frame does not rise and fall (i.e., move up ordown on any given edge) too quickly and/or endlessly (i.e., “swing” backand forth), but, instead, comes to rest as the Frame 17 reaches anAligned state. In this fashion, the Frame 17 is always held in aconstantly Aligned position, without any user observation orintervention.

One advantage of various embodiments is that there are no closedcircuits when the Frame 17 is level or otherwise Aligned in a desiredposition, thereby generally reducing power consumption and potentiallyextending Battery 4 life. Another advantage of various embodiments isthe ability to operate the apparatus without any further Userobservation or intervention.

Alternative designs to the present invention would be readily apparentto those skilled in the art, including designs that maintain a constantsupply of current and controlling the Motor 3 or Wheel 5 via integratedcircuits or other computer or electromechanical control. One advantageof this design would be to provide the User with more control of theapparatus' activation thresholds and/or sensitivity, e.g., the angle atwhich the device is activated or deactivated, and or to permit Userselection and final placement of the device without mechanicalmodification, e.g., placing the device in the lower left, backside edgeinstead of the lower right, backside edge.

As mentioned, in an embodiment, the apparatus is placed on the lowerright, backside edge of the Frame 17, however, anyone skilled in the artwould find it readily apparent that the device could be easily used(with minimal or no revisions) to operate while positioned at any of thecorners (or even anywhere that is slightly off center) of the Frame 17.It is generally easier for the apparatus to function (due to increasedleverage) the farther the apparatus is located away from the center ofgravity of the object. Additional embodiments may permit the User tochange the Leveling Apparatus' orientation and/or speed of operationand/or Tilt Sensor activation point and/or sensitivity. For example,speed of Motor 3 rotation may be controlled through the use of aresistor or a variable resistor.

Depending upon the apparatus' width (e.g., given the small, medium orlarge version(s) and/or the type, e.g., Wheel or Surface Pressure Wheelmodels), an optional supporting device or Glide Button 16 as depicted inFIGS. 5C and 5D, of generally the same width as the apparatus may beaffixed, e.g., on the lower left edge of the Frame 17 that is oppositethe apparatus, e.g., left, so as to prevent the Frame, Work or otherobject from tilting inward on the edge opposite the apparatus or to beotherwise unstable against the wall.

The support device or Glide Button, or other number of Glide Buttons 16may be made of any suitable material that will balance the Frameproperly, i.e., substantially equally offsetting the width of theinstalled apparatus. The material may be such that it doesn't orminimally marks or otherwise mars the wall or other surfaces, forexample, Nylon or Plastic. Glides such as those used on chairs may beemployed or a custom Glide Button 16 may be appropriate. Alternatively,instead of a Glide Button 16, a second or other number of non-poweredGlide Wheels 23 as depicted in FIGS. 5A and 5B may be constructed ofsimilar materials to that of Wheel 5 and could be attached, e.g., to thelower left backside of the Frame 17 to provide smooth movement of theedge opposite the apparatus on the Frame 17. A Guide Wheel 23 would rollfreely e.g., up or down in converse reaction to the movement of theopposite edge of the Frame 17. In the event other orientations, i.e.,other than on a vertical plane, are desired, the Glide Wheel 23 would beinstalled in an orientation substantially similar to that of the affixedapparatus.

Referring to FIGS. 2A and 2B, an alternative to the Wheel 5'sorientation is disclosed. The apparatus depicted in FIGS. 2A and 2Bworks in nearly an identical fashion as that of the embodiment depictedin FIGS. 1A-1D, with one major modification, i.e., to the orientation ofthe so-called “pressure” Wheel 5. Instead of being mounted such that thenarrow portion of Wheel 5 faces and rests against (or touches) the wallas in the previously described embodiment, the flat or wide portion ofthe Wheel 5 faces and comes into contact with the wall as seen in FIG.2B using wheels oriented in a flat position, relative to the wall orother mounting surface as seen in FIGS. 2C and 2D using Wheel 5. Thereare at least four advantages to this orientation of the Wheel 5: 1) Bypositioning the Wheel 5 so that a larger surface area of the Wheel 5 isin contact with the wall, greater friction may be generated, therebytransferring more of the Motor's 3 energy into vertical (or otherdesired directional) movement, 2) the Wheel 5 may have additionalabrasive elements added to its larger surface area such as raised “nubs”or “rings” as depicted in FIGS. 2C and 2D respectively 3) thisalternative position or orientation of Wheel 5 effectively reduces theoverall width of the apparatus and, therefore, the distance that theFrame 17 is pushed away from the wall or other mounting surface and 4)this reduction in width also effectively changes the relative size ofthe optional Glide Button(s) and/or Glide Wheel(s), if used.

Referring to FIG. 4A, an optional enhancement to the apparatus may bethe inclusion of a Solar Charger, which includes a Photovoltaic Cell 7that may be positioned and affixed to the top edge of the apparatus orthe top edge of the Frame 17, or anywhere ambient or other light mayfall. The Photovoltaic Cell 7 may provide ample power to operate thedevice without the use of a Battery 4, and/or, to serve as an aid tohelp extend the useful life of a battery. Moreover, a Charging Regulator8 may be included in the Solar Charger to both regulate the chargingrate provided by the Photovoltaic Cell 7 and to guard againstovercharging the Battery 4. Simply increasing the length of the wiresattached between the Photovoltaic Cell 7 and the apparatus' enclosure 19(FIG. 1.a) may accomplish remote placement of the Photovoltaic Cell 7.In this case, additional adhesive tape, mounting brackets or otherhardware, e.g., a separate enclosure, may be optionally added to theSolar Charger.

Referring to FIGS. 5C and 5D, as previously mentioned, the LevelingApparatus' width may be countered with the attachment of a slide orGlide Button 16 or, alternatively as seen in FIGS. 5A and 5B a GlideWheel 23. Affixing either device to the Frame 17 in the bottom backsidecorner, opposite the Leveling Apparatus, e.g., as depicted in FIG. 5C,the Frame 17 will remain equidistant from the wall at both corners ofFrame 17 in an esthetically pleasing position. An additional benefit ofthis arrangement is that the Frame 17 may be more equally distant fromthe wall at all four corners. Finally, adding a Glide Button(s) and/orGlide Wheel(s) may reduce friction between the wall and the corner ofthe Frame 17 opposite the Leveling Apparatus, which, in turn, willreduce power requirements, consumption and wear and tear on the Motor 3.

The Glide Button 16 may be affixed to the Frame 17 using adhesive doublesided tape 26 as shown in FIGS. 5C and 5D or a Glide Pin (or nail ortack) may be used (not shown), or, absent double sided tape or a pin, itmay be affixed using commercially available temporary or permanentadhesives. Glide Button 16 may be made of a plastic resin, nylon orother semi-pliable or ridged material commonly used with so-called chairglides such as the chair glides manufactured by International EquipmentComponents of Signal Hill, Calif. e.g., their Light Duty, Nylon Base(round tubing), with nail (i.e. pin) chair glide, as their Part No.IL22-R1.

The Glide Wheel 23 may be constructed similarly to the pressure Wheel 5and may be of the same or smaller size than Wheel 5; however it shouldbe constructed in combination with the Glide Wheel Bracket 24 and GlideWheel Adhesive Tape 25 such that, in combination, the entire assemblymaintains the Frame 17 at a distance generally equal to the overallwidth of the Leveling Apparatus. Glide Wheel 23 may be affixed to Frame17 using Glide Wheel Adhesive 25, which may be double sided adhesivetape, or absent Glide Wheel Adhesive, via a bracket mounting holes andscrews or nails, using any commercially available wood screw or otherscrew or nail of an approximate length, which is less than orsubstantially less than the depth of the Frame 17 but still of anappropriate length to ensure that the Glide Wheel 23 remains firmlyaffixed to Glide Wheel 23 and Frame 17.

Instead of a DC Motor, various other means for rotating a wheel, gear orother components may be substituted for the DC motor. For example, an ACMotor may be directly attached to a turning wheel with power suppliedvia a common household electrical plug and power converter ortransformer.

Also, instead of a Wheel 5, other components may be employed toselectively move a portion of an object (e.g., a corner of a frame) in amanner that aligns the object (e.g., moves the corner up or down). Forexample, a ball of an appropriate diameter or a cylinder of anappropriate diameter and length could replace the Wheel 5.

The principles and apparatus described herein may be readily employed tomaintain an object's alignment with other planes besides the horizontalplane. For example, embodiments of the invention can be readily employedto achieve alignment with any arbitrary angle (e.g., a plane that formsan angle of five degrees or 90 degrees with the horizontal plane). Itwould be readily apparent to anyone with ordinary skill in the art thatthe tilt switch may be manually aligned (or in some cases,electronically or programmatically adjusted or aligned) in any desirableorientation or axis, including multiple orientations or axes.Consequently, the apparatus may be designed or used to maintain anydesirable alignment as compared with any fixed point in space.

It will be readily apparent to anyone with ordinary skill in the art asto the electrical components, wiring and other modifications necessaryto add an audible notification device such as a beeper or buzzer and/ora visual notification such as a steady or flashing light to theapparatus. The addition of a buzzer, beeper or other audible and/orvisual notification device(s) may add a pleasing effect to the overalloperation of the apparatus such that the User may be made aware of theapparatus' operation and may observe or point out to other bystandersthe apparatus as it automatically aligns the object or frame. Suchoptional notification device(s) would typically not be an ongoingnuisance as the apparatus would generally be in a stable or alignedposition; therefore, the notification device(s) would generally only beactivated when the apparatus is in actual operation.

Additional benefits of notification device(s) are: 1) in the event aperson or other outside force, such as the wind, moves or otherwisedisturbs the alignment of a Frame or other object, a sound and/or lightwill be generated, which might prove useful in a personal residence orin an art gallery or museum, 2) such notification device(s) may serve asa warning or alarm to deter unauthorized persons from disturbingvaluable items, and 3) should one or more components in the apparatusfail, which causes the device to swing or otherwise fail to achieve thedesired alignment, the notification device may alert the User to such afailure of the apparatus. A buzzer could be used such as onemanufactured by Radio Shack of Fort Worth, Tex. as their Model #:273-054, Catalog #: 273-054. A light could be used such as a LightEmitting Diode such as one manufactured by Radio Shack of Fort Worth,Tex. as their Catalog #: 276-350.

It will thus be apparent that there has been provided in accordance withthe present invention a Leveling Apparatus with an integrated TiltSwitch and, ideally, a Dual Throw, Dual Pole Tilt Switch, which achievesthe aims and advantages specified herein.
